Multi-particle-based multi-party controllable quantum secure dialogue

Year: 2024

Type: article

Abstract: Based on the six-particle entangled state, this paper proposes a multi-party controllable quantum secure dialogue protocol, where the dialogue parties only need to perform single operation to efficiently encode secret information and embed the control information into a fixed particle sequence in order, ensuring the orderly transmission of information. Additionally, the protocol introduces a unique honesty detection mechanism, which relies on the classical XOR relationship of three qubits in a GHZ-like state, effectively guaranteeing the credibility of the controllers. The protocol allows two dialogue parties to synchronously obtain secret information with the permission of all controllers, without relying on additional classical channel, greatly enhancing communication efficiency and security. Through rigorous security analysis, it is proven that the protocol can effectively resist various potential attacks from both internal and external sources.
